Technology alarms
Description
If an error occurs at a technology object (e.g. approaching a hardware limit switch), then a
technology alarm is triggered and indicated. The impact of a technology alarm on the
technology object is specified by the alarm reaction.
Alarm classes
Technology alarms are divided into three classes:
●
Warning (can be acknowledged)
The processing of Motion Control jobs continues. The current motion of the axis can be
influenced, e.g. by limitation of the current dynamic values to the configured limit values.
●
Alarm (must be acknowledged)
Motion jobs are aborted in accordance with the alarm reaction. In order to continue job
processing after resolving the cause of error, you must acknowledge the alarms.
●
Fatal error
Motion jobs are aborted in accordance with the alarm reaction.
To be able to use the technology object again after eliminating the problem, you will need
to restart the technology object (Page 197).
